Who would want a 6.2 in a Corvette?Raise your hand for a count.

My wife's c7 has one.

Did you notice that my hand was raised?

Here is an interesting video with insider info on the problem (crankshaft) and why they are shifting production.

Who would want a 6.2 in a Corvette? Raise your hand for a count.

The vast majority of C6, C7 and C8 owners apparently do. LS3, LS9, LT1, LT2, LT4, LT5, let's see, did I miss any 6.2L corvette engine variants?

I really want an LS3 C6 manual. Probably another decade before I can buy a toy like that though, we'll see.

Hey, my hand is raised. I get to drive it on vacation. Sometimes.

Here is the test procedure to see if you get an new engine or an oil change. It must be using the knock sensor to pick up issues with the crank bearings.

It is too bad for the ones involved in the recall. My wife's new 2025 Tahoe High Country with the 6.2L is not involved with the recall. Compared to the 5.3L we drove for a test it is night and day for power. It is fun to drive but you do have to watch your speed. It gets up to speed fast, cruise control is my friend.

According to the GM website, my 2022 GMC Sierra 1500 is involved with the recall. I have not yet received the recall notice. I wonder how long that will take?

It took over a year to receive the notice for the defective grille recall. The replacement part has been on backorder for 4 months now.

I usually trade in my vehicles every 3 or 4 years. I may wind up doing so before either recall is fixed.

Here is the test procedure to see if you get an new engine or an oil change. It must be using the knock sensor to pick up issues with the crank bearings.

I think that’s one of three different tests used, depending on your serial number. Some others get a simple check for a code:

I wouldn’t want to have mine judged by either method.

General Motors Facing New Class-Action Lawsuit Over 6.2-Liter V8 Issues

The lawsuit was filed in the U.S. District Court for the Eastern District of Michigan.



The lawsuit, featuring plaintiffs from Washington and California, details familiar issues with the L87 engine, specifically in vehicles manufactured for model years 2021–2024. As outlined in that April recall, the engines may feature sediment on the connecting rods or in the oil galleries for the crankshaft, which can lead to rod-bearing damage. GM has also acknowledged some engines may feature a crankshaft that is out of production spec. Any of these issues can result in a catastrophic engine failure.
